I'm guessing u ment that the ratio was 4:3
so you do 35 divided by 7 (4+3) = 5
4 times 5 =20 (boys)
3 times 5 = 15 (girls)
so there are 5 less girls than boys
12
57 oops ! That's the boys. There are 95 girls.
With a ratio of 7:4 there are 7+4 = 11 parts - 7 parts are girls, 4 parts are boys. 77 students / 11 parts = 7 students/part Girls are 7 parts → girls = 7 students/part × 7 parts = 49 students For the ratio of girls : students, you can either use the figure just found: 49 : 77 = 7 : 11, or just go back to the original ratio: 11 parts are students, 7 of those parts are girls → ratio girls : students = 7 : 11
Well, if the ratio of boys to girls is 4 to 3, that means there are 4 parts boys and 3 parts girls out of a total of 7 parts. So, the boys make up 4/7 of the total students, and the girls make up 3/7. With 910 students, that means there are 520 boys and 390 girls. So, there are 130 more boys than girls in the school.
3+7=10 (3 and 7 are both ratio numbers) 420/10=42 (10 is the sum of both ratio) 3x42=126 girls (3 is ratio of girls) 7x42=294 boys (7 is ratio of boys)
1515 girls

To find the number of boys in the class, we first need to determine the total number of students. Since the ratio of boys to girls is 5 to 8, the total parts of the ratio is 5 + 8 = 13. If there are 40 girls in the class, we can calculate the total number of students as 40 girls / 8 girls per part = 5 parts. So, the total number of students is 5 parts * 13 total parts = 65 students. To find the number of boys, we can calculate 65 total students - 40 girls = 25 boys in the class.
50 students
With a ratio of 7:4 there are 7+4 = 11 parts - 7 parts are girls, 4 parts are boys. 77 students / 11 parts = 7 students/part Girls are 7 parts → girls = 7 students/part × 7 parts = 49 students For the ratio of girls : students, you can either use the figure just found: 49 : 77 = 7 : 11, or just go back to the original ratio: 11 parts are students, 7 of those parts are girls → ratio girls : students = 7 : 11
9 boys
There would be 6 boy students and 18 girl students in the class.

If the ratio of girls to boys is 5 to 4, this means that out of every 9 students (5 girls + 4 boys), 5 are girls and 4 are boys. To find out how many girls there are in the class, you need to divide the total number of students by the total parts of the ratio (5 + 4 = 9) and then multiply that result by the girls' portion of the ratio (5/9). So, in this case, there would be (5/9) * 90 = 50 girls in the class.
If the ratio of boys to girls is 12 to 3, then the total ratio is 12 + 3 = 15. To find how many girls are in the class, we divide the number of girls by the total ratio, 24 / 15 = 1.6. This means there are approximately 1.6 girls in the class. However, since we can't have a fraction of a girl, we can conclude that there are 2 girls in the class.
There is 48 Girls and 51 boys
